摘要/Abstract

摘要： 基于芳香基双硫键，以聚丙二醇-4000（PPG-4000）和异佛尔酮二异氰酸酯（IPDI）为原料，双（4-氨基苯基）硫醚为交联剂，乙酸酯化纳米纤维素作为增强相，制备得到乙酸酯化纳米纤维素/聚（脲-氨酯）[esterified cellulose nanocrystals/poly（urea-urethane），E-CNCs/Pus]自愈合复合材料。对其力学性能、热学性能、表面化学结构、自愈合性能进行了表征研究。结果表明，E-CNCs/PUs在室温下不需其他额外条件即可实现自愈合，说明芳香基双硫键可作为动态交联键应用于自愈合聚（脲-氨酯）的设计与构建；E-CNCs添加量为0.1%时，其聚（脲-氨酯）复合材料拉伸强度达到5.71MPa，与纯聚（脲-氨酯）材料相比，增加了43.11%；E-CNCs/PUs复合材料不仅具有较高的拉伸强度，而且保持了良好的弹性和延展性；热学性能分析结果表明，E-CNCs对聚（脲-氨酯）复合材料热稳定性具有较小影响。

Abstract: In this study,the esterified cellulose nanocrystals/poly(urea-urethane)(E-CNCs/PUs) self-healing materials were prepared using polypropylene glycol 4000(PPG-4000) and isophorone diisocyanate(IPDI) as raw material,bis (4-aminophenyl) sulfide as crosslinking agent,and esterified cellulose nanocrystals as reinforcement. The mechanical properties,thermal properties,surface chemical structures,and self-healing properties were investigated. The results show that E-CNCs/PUs were self-healing effectively at room temperature without any external interventions,which confirms that bis(4-aminophenyl) disulfide can be effectively used as a dynamic cross-linker for the design of self-healing poly(urea-urethane) material. The maximum tensile strength of E-CNCs/PUs could reach 5.71MPa when the additive amount of E-CNCs was 0.1%,which was increased by 43.11% compared with pure poly(urea-urethane). E-CNCs/PUs composite materials present high tensile strength,elasticity,and malleability. The additive of E-CNCs just has a small influence on the thermal properties of E-CNCs/PUs self-healing materials.
